DIE FOR FINISHING BOTTLE-CAPS.

To all whom it may concern.-

Be it known that 1, CHARLES E. McMANU's, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Dies for Finishing Bottle-Caps, of which the following is a specification.

"This invention relates to im rovements in dies for forming tongues-or loc ing members upon the rims or flanges of bottle-seals of the cap ty e, and particularly to a die for forming in ented or instruck tongues upon bottlecaps of the type shown in my r101 United States patent, No. 772,250, dated October 1 1, 1904 wherein the tongues on the rim of the ca are adapted to.be passed downward throug spiral grooves formed in a flan e or enlargement upon the mouth of the ottle and to bear beneath said flange to secure the bottlecap in place. I do not, however, limit the invention to forming tongues of the specific construction shown in said patent, as it may be used for making locking members of any other desired form.

The object of the present invention is to provide a construction of die whereby the successive operations of forming the tongues upon the caps fed thereto and ejecting the finished caps may be efliciently and speedily performed, so that a maximum number of ca s may be finished within a given time.

ith the above and other objectsin view the invention consists of the novel features of construction and combination of parts hereinafter fully described and claimed, reference being had to the accompanying drawings,i in which Figure 1 is a side elevational view of the die and cap-support. Fig. 2 is a'vertical section of the same. Fig. 3 is a top lan view thereof. Fig. 4 is a similar view 0 the capsupport. Fig. 5 is a bottom plan view of the die. Fi 6 is a similar view with the pivoted die mem ers on the head removed. Fig. 7 is a detail view of the pivoted die members and carrier-ring, and Fig. 8 is a perspective view of a finished cap.

Referring now more particularly to the drawings, the numeral 1 designates. a worksup ort comprising a bed-plate 2, provided wit an upwardly-extendin boss or anvile head 3, formed in its upper ace with a seatrecess for the reception of a cap receiving and supporting socket 4, having a chamber corresponding in depth and diameter to the cap tongues to be formed upon t downwar ward. The head 17 is provided in its under to be-operated upon and in which the cap is inserted in inverted position with its top resting upon the bottom wall 5 of said socket and its flange or rim resting against the annular side wall 6 of the socket, which side wall 6 is formed at intervals with slots or recesses 7.

The die 8 is of the reciprocating type and comprises a head 9, provided with an upwardly-extending tubular shank 10, adapted 'to be clamped to the chuck or die carrying part of any suitable dieoperating mechanism. Arranged upon the outer surface of the head are stationary die members 11, com.- rising elongated blocks fixed to the head y screws or but which may be formed integral with the other preferred fastenings 13,

head, if desired. The lower ends of these die members pro ect'below the head and provide forming portions 14,- adapted upon the downward movement of the die to enter the recesses 7 in the socket 4 and provided upon the inner faces thereof with stepped formin surfaces, which may vary in number, accor ing to the depth of the ins ringing lockinge mm of the cap. Movable loosely in the die-body and shank is a su porting-stem 15, provided at its upper en with a check-nut 16 to limit its downward movement and carrying at its lower end a head 17 movable between the forming members 14 of the dies 11. A pressures ring 18 is coiled about the stem 15 within t e head and bears, res ectively, at its lower and upper end against s oulders formed up on the body and stem, said spring'serving to normally roject or force the stemand head (i and permit the same to yield upside with a series of radial slots 19, corresponding in number to and alining with the forming members 14, and seated within these slots are movable die members 20, having outer forming surfaces or recesses 21. These movable'die members are ivotally mounted adjacent their inner en s upon pins 22, mounted 'upon a slotted carrier-ring 23, occupying a'recess in the head at the point of intersection of the slots, 19. This manner of pivotally mountin the die members 20 adapts them to f0 (1 horizontally into the slots 19 and to tilt downward at their outer or forming ends to release the cap 1n the manner hereinafter described. A pin 24, carried by the head and projected outward by a spring 25, seated in a socket in the stem 15, engages the inner ends of the dies 20 and exerts pressure thereon tov normally hold .the

same in a horizontal position. Slidably mounted inthe head are cap' releasin or extracting pins 26, limited in downwar movement by stop-shoulders 27, adapted to engage the head and provided between said I vertically movable in the openings in the bed and bottom of the socket 4 and normally pressed upward by springs 31, seated in suitable receiving recesses or sockets'in the bed. In operationthecaps are successively fed -to the socket 4 by hand or any suitable type of feed mechanism and are disposed in in-' verted position in said socket. U on the downward movement of the die the cad 17 enters the cap and causes the die members to clam the rim of the. ca against the side wall 6 o the socket 4 and the pins .26 to bear upon the top of the cap and in coniiunction with said die members 20 clamp t e same against the bottom socket-wall5. As the (he continues to descend the head 17 folds against the bottom of the bod 9 and between the forming members 14 0 the dies 11,

which members 14 come down u on the outside of the rim of the cap and in ent orforce the portions thereof engaged thereby into the recesses and against the formin -shoulders of the die members 20, thereby orming the tongues '32 upon the cap 33 as shown in F 8. It will be understood that upon the downward movement of the head the pins 30 'will be forced downward, under the ressure of the head to allow the cap to be eld securely Within the socket during the operation offorming the tongues. Upon the upward movement ofthe die the die members 11 will first be withdrawn from engagement with the of the cap, the head 17 remaining in position until the nut 16 isengaged by the shank 10 to hold the cap in position until the die moves u: ward a sufficient extent for its dischar e war movement of the head the pins 30 Wlll lift the finished cap from the socket, while the pins 26 will force therim of the cap out of engagement with the die members 20, the term ends of the latter tilting downward under t e pressure of said ins to release the rim of the cap and permit t elatterto be discharged; In practice it is found that the actlon of the springressed releasin -pins is sufficient to force t e finished cap om the socket and out of engagement wlth the die, so that it fall from the anvil 3 onto the bed plate or support, to which the latteris speed.

om the socket 4. Upon the upenter ti;

the said tractin means ma be employed, if desired;

By t e use of a ie of the construction described a'maximum number of caps'may be operated upon within a given time,.as the uick release of-the finished caps permits the die to be operated at a very rapid rate of Having thus described the is claimed as newjisinvention, what 1.
